摘 要:通过对1980,1995,2006年顺义区农田景观规模和空间格局演变的分析,总结出其作为典型的大城市近郊区域农田景观变化的显著特征:第一,农田景观规模呈加速缩减趋势,农村居民点等低密度建设用地是侵占农田的主体;第二,农田景观斑块的空间重心由原来较为居中的位置,持续向远离城市组团中心的东北方向移动;第三,从全境镶嵌体和农田单一景观水平上分析,其景观格局演变均呈破碎化、离散性和均一化趋势。顺义区农田景观因社会经济结构和区域发展方向的调整而发生巨大改变,被道路和大量小规模的无序建筑侵占和切割,正在逐步丧失农田景观美感,应通过探索不同模式的农田景观治理和建设途径,对城市近郊农田景观加以保护和利用。The paper summarized the evolvement characteristics of typical big city suburb regions based on analyzing the evolvement process of farmland landscape size and spatial pattern in 1980,1995 and 2006. The results showed that, firstly, the size of the farmland landscape presented accelerated diminishing, and the rural residential areas and other low density construction land are the subjects which embezzlement farmland; Secondly, the spatial center of gravity of farmland landscape patches moved from the middle position to the northeast direction, far from the center of the urban agglomeration; Thirdiy, based on the region mosaic and the single landscape levels, the landscape pattern presented fragmentation and homogenization simultaneously. With the adjustment of the social economic structure and the regional development direction, the farmland landscape of Shunyi occurred significant change. The farmland landscape lost aesthetic feeling gradually by embezzled and cut by roads and mass disordered building. We should protect and use the farmland landscape of the urban suburban reasonably through exploring the different pattern of the farmland landscape treatment and construct.
